  12. Roadbed Integrity Warning System

  13. Recommendations Nakina (1992) & Conrad (1997) • Identification of sites susceptible to slope instability • Review of current roadbed design criteria • Adequacy of existing drainage systems • Systems for monitoring roadbed integrity

  14. Transport Canada Working Together onRailway Natural Hazards IRSC Conference Tokyo, November 2002

  15. Transport Canada’s Role Develop and administer policies, regulations and services for thebest transportation system in the world for Canadians

  16. TC Roles In Innovation Cycle • Gather intelligence • Set safety standards & monitor compliance • Do research and development • Promote & fund innovation by external partners • Broker and manage national & international partnerships • Develop national visions and focus initiatives & resources • Integrate innovations into its own operations

  17. TCR&D Project Origins • TC • Other federal government departments, agencies, and programs • Provinces • Industry • Foreign governments • Visionaries

  18. The Natural Hazards Problem: How to economically identify conditions that might be hazardous to train passage through rugged mountainous terrain and provide countermeasures.

  19. Landslide Hazard Risk Mitigation

  20. Electromagnetic Field Disturbance Rockfall Detection System CN Lasha, near Lytton, B.C. CP near Golden, B.C. Instrument Case for test equipment Cable laid on wood ties, protected by 2” x 4”s Cable laid on concrete ties, protected by conduit

  21. RRAB Workshop Slide and Washout Hazards:Managing Natural Risks on RailwaysMay 1-3, 2002

  22. Purpose of the Workshop Stimulate collaboration and the investment of resources for new developmental programs to improvethe management of natural risks from slide and washout hazards on railways

  23. Workshop Sponsors • Association of Regional Railways of Canada • Canadian National Railways • Canadian Pacific Railway • Industry Canada • National Research Council • Natural Resources Canada • Office of Critical Infrastructure Protection and Emergency Preparedness Canada • Railway Association of Canada • Transport Canada • VIA Rail Canada

  24. Workshop Discussion Groups • Hazard characterization • Establishing the context for research • Hazard monitoring and detection technologies • Research needs and priorities • The way ahead

  25. Workshop Will Be Considered aSuccess When. . . • New programs are planned, resourced, andbegun within one or two yearsto tacklepriorities identified in the workshop • Significant improvements in managing naturalrisks from slide and washout hazards on railwaysare implemented and are bearing significant fruit within five years that trace their origins to the workshop

  26. Planned Workshop Follow-Up • Prepare and distribute: • Full workshop proceedings • Package of speaker’s overheads • Prepare and circulate proposed program: • Initial sounding with expert panel members • Circulate results to all participants • Consult with participants on proposed program • Develop and implement go-forward plan: • Converge on supportable program • Resource the program • Form technical steering group & management regime • Coalesce participants and partners

  27. Ground Hazard Research Program • Risk Assessment • Hazards classification system • Database of incidents and case histories • GIS based modeling tools for predicting events • Critical weather thresholds that trigger events • Field test methodologies for the Fraser Canyon and Thunder Bay rail corridors • Risk Control • Decision support tools for mitigating risk • New technologies for monitoring and detection of events
